To all 207mm 2'2. may concern Be it knownthat 1,. KARL lVINKLnn, a citizen of the German Empirepresiding in Jersey City, in the countyof Hudson and 6 State of New Jersey, have invented certain new and useful Improvements in Bristle- Feeding .i-rttachment s 'for Brush-Making Machines, of which the followingis a'specification. 1

attachments for brush-making machines by which the bristles, fibersorother material are formed into tufts of uniform size and suppliedin a reliable manner to the tuftfilling devices, so as to be inserted into the holesbored into the brush-backs. The object offthisinvention is to provide a bristle-feeding attachment in which the supply of bristles "orfibe'rs for the brushtufts/can be kept up continuously without stopping the machine, and by which the necessary number of tufts of uniform. size is formed and supplied to the brush-back'filling devices. whatever be the speed at which ,d-band in saga; boil.

Referring to the drawings. a represents a bristle-feed box, which is made of oblong shape and-which is supported in proper position "relativ-"elv to the tuft-filling devices of the bruslrniaking machine so as to deliver the tufts'of bristles formed by the attachment directly tosaid filling devices.

In the bristle-feed bo x ii is arranged an end-lesslongitudinal feed-band Z), which is driven in the direction of the arro w shown in F ig. 1, by a driving-roller 7) at one end and guided by a guide-roller 7)? at the opposite end of the feed-box.

The feed-band Dis held tight by means of gu'deEroller L -bel'ow the driving-roller 5 which guide-roller acts onthe lower part of the fe'ed ba d whilei'thje'iipper partof the feed band '1S' i roller "The'.-iippe1 horizontal portion of the feed-band is supported on a longitudinal 95 a bar The endless band 6 is provided with. a center-groove b", while "the Presser-roller (Z is provided with a center-groove rl which is in register with the center-groove of the The bristles are fed in forwardfeedband'. direction by; the feed-band and guided by a longitudinal guide-piece c; which is adj usted 011 the feedjb'ox by means of slotted straps c and set-screws 6 as shown in Fig. at. A second bristle gulde-piece may be arranged at theiopposite side of the feed-bainl. though one guide-piece sufficient for inost purposes so as to give a certain pla v to the opposite ends of the bristles in being moved forward by thefeed-band. The bristles are led forward by the feed-hand aud'pasa-il bc't\ vcen the same and the pi-e. er-rollcr (I fi'ntoa briAle-receptacle which i arranged acted upon bya rotary presser f-ifeedbox a, and which are provided at their vertically above the driving-roller b and presser-roller (Z. The end-walls f of the bristle-receptacle f are provided with clearers P which extend respectively into the longitudiual groove of the feed-band b and into the circumferential groove of the presser-' foilter ends with knobs or handles f for permittin g the adjustment to the length of the I b ristles fed into the bristle-box. At the upper .end of the bristle-receptacle f is supported ,on a bracket g? a horizontal guide.- plate 9 on which is guided a reciprocating slide-plate. g which is provided in its underside with a transverse groove 9 which, in passing over the upper end of the bristle-receptacleand the horizontal guide-plate 9 is filled with bristles from the body of bristles which is pressed in upward direction in the ,brist-le'receptacle by the feed-band and presser-roller so as to form a tuft which is delivered over the guide-plate'to the filling. devices of the. brush-making machine. The; slide-plate g is guided in a guide-box g on top of the bristle-receptacle f, said guide-box having an oiler 0, and the slideplate is actuated by means of a lever 9 which engages by its slotted end the rearend of the slide-plate and transmits reciprocating--motion to the slide-plate by the oscillating motion imparted to the lever in any suitable manner.

Longitudinal forward feeding motion is imparted to the feed-band Z) and its drivingroller 6 by a belt-and-pulley transmission from an overhea 1i shaft first to the pulleyshaft 3 and then by a worm w on the pulleyshaft and a worm gear-wheel w to an intermediate shaft 8 The shaft 8 is arranged at right angles to the pulley-shaft s and transmits by gear-wheels 202, w rotary motion to the shaft 3 of the driving-roller b of the feed-band, as shown in 'Fig. 4:. The presser-roller d is rotated by the shaft 8 which passes transversely through the feed-box a. Between the hub of the gear wheel 10 and a boss '10 on the inner sidewall of the bristle-feed box a is interposed a ball-bearing h, while a second ball-bearing h is interposed between the hub of the worm gear-wheel w and the hubk of ashort hollow shaft 8 which'turns in bearings of a standard k A- friction-disk h keyed to the shaft 8 presses on a yielding disk k in a recess in the hub of the worm gear-wheel 'w while the outer tapering end of the hub k is acted upon by the toe-piece lit-of a fulcrumed and weighted lever h.

\Yhen too great a quantity of bristles is fed into the bristle-receptacle f, the pressure in the same becomes too great and the rotary ninotlon imparted to the drivmg-roller is retarded by the. free turning of the worm gear-wheel Q01. between the. ball-bearing h and the friction-disk h so that the transmission'of motion by the gearqvheels 10 20 to the driving-roller and feed-band is interrupted. By this arrangement the regular supply of bristles to thebristle-receptacle and to the tuft-forming slide-plate is retarded 'or entirely discontinued until the overpressure of the bristles in the bristlereceptacle is relieved by the action of the slide-plate and the regular "feed motion of the bristles resumed. The reciprocating motion of the slide-plate which has to supply. from 100 to 120 turts per minute, is

thereby regularly and automatically kept up without any danger of interruption by overpressure on the bristles in the bristlereceptacle. The bristles are of sufficient length tov permit their doubling .up into tufts for being inserted into the socketholes of the brush-back by the filling devices of the' brush-making machine. As the weight k of the counterbalanced pressurelever ll is adjusted fora certain amount of pressure in the bristle-box, it is obvious that as soon as this pressure is reached, the rotary motion of the presser-roller is interrupted by the interposed'friction devices on the shaft 8 while the proper supply of bristles to the bristle-receptacle is automatically restored as soon as the overpressure in the same is relieved by the action of the slide-plate g. By this arrangement the automatic continuous and reliable feeding of the bristles to the tuftrforming groove of the slide-plate and the uniform formation and supply of tufts to the filling devices of v the brush-making machine is secured.

As. the supply of bristles to the open'or supply end of the bristle-box can be readily kept up from time to time by supplying a new quantity of bristles, and as the feeding.

of the bristles to the bristle-receptacle and reciprocating slide-plate is kept up uni formly, a full, regular and continuous sup ply of tufts of bristles to the bristle-filling devices of the brush-making machines is ob-- tained, so that the brush-making machine can be kept running to its full capacity with a'c'ontinuous and full supply of tufts for filling the brush-baoks in the machine; I claim:
